1. A method of self-expanding a Layer 3 (L3) fabric of a communication network comprising one or more spine switches having a leaf-spine topology, the method comprising:
until a reply to one of a plurality of probe messages is received, periodically transferring the plurality of probe messages from each of the one or more spine switches to a network address from a pool of one or more network addresses reserved for discovering computing nodes to be added the L3 fabric, wherein the pool limits a number of network addresses to which probe messages are sent for discovery of the computing nodes;
receiving the reply to one of the probe messages from a new computing node at the network address;
in response to the reply, incorporating the new computing node into the L3 fabric, wherein incorporating the new computing node includes assigning a new network address not in the pool to the new computing node; and
after assigning the new network address, resuming periodic transfer of the plurality of probe messages to the network address until a second reply is received to another of the plurality of probe messages from another new computing node at the network address.
